Side Bars and WordPress breakdowns

As no doubt anyone passing by has noticed I have lost my sidebars. The left is floating around the bottom of the page and the right with search, comments and post has disappeared altogether as I accidentally deleted the whole of the right instead of one piece of script.

I have tried to figure it all out but so far with no luck. If anyone out there can help me put this back together I would be eternally (well not quite but definitely enormously) grateful –
